Grab as many treasures from the cursed ancient ruins as you can, and get out safely before you get eaten by bugs, fall down a pit, die of thirst in the desert, or get ripped to pieces by a mummy. I was never fully sure of the game's mechanics but still found it enjoyable throughout, with it's mildly comic tone falling somewhere between the more serious Infidel and the more silly The Horrible Pyramid, to name two other grave-robbing adventures. I finally escaped with my life and £150 to my name. Lots of opportunity for replaying here, trying to maximise your winnings in the style of Captain Verdeterre's Plunder. Fun.
As a pure text adventure, it's passable: a standard short horror story with a twist of the type that now litters the internet. The parser is awkwardly non-standard (use LOOK ROOM, LOOK <object> and GO <location> instead of LOOK, EXAMINE and compass directions) and causes initial frustration.
But it's not a pure text adventure, it's displayed on a monitor screen attached to an old computer in a dark room: and this visual and sonic ambience surrounding the text is crucial to the experience, delivering the shocks and surprises so the text adventure itself doesn't need to.
This forms chapter 1 of "Stories Untold", a commercial compilation of four spooky adventures, and it sets the creepy tone very well. This chapter can be downloaded for free from Steam and GOG.
